A CORPORATION OF NEW YORK.

LAMP-SHADE.

Application filed March 21, 1917.

To all whom it may concern:

Be it known that I, ARTHUR J. TIZLEY, a subject of the King of Great Britain, and residing in the city of New York, borough of Brooklyn, count-y of Kings, and State struction for candelabra use;

Fig. 3 is an elevation partially in section of a detail of construction common to both of the forms shown;

Fig. 4 is a broken side elevation of the construction shown in Fig. 1 taken at right angles to the latter view and showing the shade in tilted position;

Fig. 5 is an elevation partially in section of a socket showing on a larger scale the securing means illustrated in Fig. 1;

Fig. 6 is a cross section on the line 6.6 Fig. 5; and

Fig. 7 is a cross section on the line 7.7 Fig. 2.

vTiltable supports for lamp shades of the present type have heretofore been universally mounted upon the lamp globe. This practice is objectionable not only from the standpoint of injury to the lamp but also from that of security for the shade inasmuch as the highly glazed surface of the lamp affords a very poor purchase-even for a relatively strong frictional grip. My invention affords a support which is carried not from the lamp globe but from the socket casing or some analogous part of the fixture affording a substantial purchase for the shade frame.

In the construction shown in Fig. 1 the lamp 10 is mounted in an ordinary socket 11 screwed to the end of the conduit 12. Surrounding the la'mp-receivin end of the socket is a supporting ring 13 from the opposite sides of which extend upwardly the carrying arms 14 to which the lamp shade frame 15 is pivotally jointed at 16, This Specification of Letters Patent.

pivotal connection is illustrated on a larger scale in Fig. 3. It comprises a bearing block 17 riveted to the rib 18 of the frame 15 and pierced to permit the passage therethrough of the end of thecarrying arm 11. A friction shoulder 19 is formed on or secured to the arm ll and bears against the inner face of the block 17, the frictional engagement thereof being determined by the strength of a spring 20 interposed between the opposite face of the block and a head formed at the end of the supporting arm ll. In order that the axis of support may lie at right angles to that of the shade, the upper end of the arm 14: is ofiset at 21 and the inclined rib 18 is offset at 22, so that the portion thereof to which joint is made is substantially parallel to the axis of the shade, The offsetting of the rib 18 22 has the additional advantage that it provides a chamber 23 which accommodates the spring 19 and arm end without interfering with the appearance of the shade cover 24 whic}; passes the joint 16 with unbroken outline. a

The supporting ring 13 has a constricted upper edge 25 adapted to engage the usual bead 26 at the lamp receiving end of the socket, while tongues 27 struck inward from the sides of the ring engage the opposite side of the bead and thus retain the ring in position against accidental displacement. in order to support the opposite margin of the ring 13 I provide a split collar 28 having a bead 29 of substantially the,same height asthe bead 26 on the socket and which may be slipped over the socket before the ring 13 is adjusted in position. It forms merely a steadier for the ring as will be obvious from. an inspection of the construction as illustrated in Fig. 5.

The construction in Fig. 2 is analogous to that above described in so far that it comprises a carrying ring 30 adapted to be passed over the coned upper end of a candle tube 81. Tongues 32 are struck inward to It still more sceure mounting may be provided by fastening the arms ll to a screw ring which threads upon the end of the lamp socket, and this construction is also emplayed by me in certain installations in which e: eptional rigidity is desired.

Various modifications in detail of construction and arrangement of parts Will readily appear to those skilled in the art which do not depart from What I claim is my invention. In the following claims I use the expression socket casing in a sense broad enough to cover a candle tube, or any analogous part upon which the frame may be conveniently supported.

I claim as my intention 1- 1. A lamp shade having a skeleton rib frame, a pair or" carrying arms jointed to opposite ribs intermediate the ends of the latter and frictional means automatically maintaining the shade frame in the position to which it is tilted with relation to said carrying arms Bi lamp shade having frame ribs with offset reaches therein, and a pair of supporting arms frictionally jointed to said ribs at the ott'est reaches.

ciiued to the axis of the shade but having offset reaches parallel to said axis and a pair of supporting arms frictionally jointed to the ribs at said offset reaches.

-ii. A lamp shade having frame ribs inclined t0 the axis of the shade but having oiiset reaches parallel to said axis and a pair of supporting arms frictionally jointed to the ribs at said offset reaches, and at substantially right angles to the axis of the shade.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing Witnesses.
